Vidic: Don't rule out Ronaldo's return to Old Trafford after he's done at the Bernabeu

Nemanja Vidic has refused to rule out the possibility that he could one day be reunited with Cristiano Ronaldo at Manchester United.

The Red Devils centre back will face off against his former team-mate when Sir Alex Ferguson’s men take on Real Madrid at Old Trafford in the second leg of the last-16 Champions League tie.

But despite his manager claiming the prospect of Ronaldo return in the red of United is implausible, Vidic believes it is a possibility.

Not impossible: Ronaldo could return to Old Trafford, according to his former team-mate Vidic

The 31-year-old Serbian told the Daily Telegraph: ‘I could see it [Ronaldo’s return to Manchester United]. He is a United supporter and he still follows United, he still misses the club and the environment here, so I wouldn’t be surprised to see him come back.

‘It would be a big ask for many reasons, but I would love to see him here.

‘I don’t know what atmosphere he has at Madrid, so I can’t really talk about that, but all I can say is that I enjoyed playing with him, he enjoyed it here and it will be great to see him.’

Vidic also believes that the Portugal captain is on par with Barcelona’s Lionel Messi, who has beaten Ronaldo to the Ballon d’Or four years in a row.

He added: 'They are different players, totally different.

'But in recent years, Barcelona have won everything and I think that is why people have put Ronaldo to one side.

'I have played with him and trained with him and I know how many sacrifices he made to be where he is.'
